Description
. .,1 Изобретение относитс к гидрометаллургии цветных металлов, в частности к способам извлечени т желых цветных металлов, например меди, никел и водных раств ров путем их осаждени в виде сульфидов. Известен способ осаждени сульфидов цветных металлов из водных растворов и пульп сульфидизадией 11 . , По этому способу вь1деление сульфидов цветных. металлов ведут серой, растворенной в какой-либо щелочи. Однако при таком способе содержание цвет ных металлов В конечном продукте пониженное , а расход реагента-осадител высокий. Целью изобретени вл етс повышение содержани цветных металлов в конечном продукте и снижение расхода реагента-осадител . Это достигаетс тем, что сульфидизацию ве дут смесьго металлического железа и серы, растворенной в щелочи., Металлическое железо, которое одновременно с раствором серы в щелочи вводитс в в раствор, содержащий цветные металлы. создает в растворе -окислительно-восстановительный потенциал, способствующий вовлечению в процесс осаждени малоактивных форм растворенной серы. При этом существенно снижаетс требуемый расход jiacTBOpa серы в щелочи, и конечный продукт в значительно меньщей степени загр зн етс выдел ющейс в процессе осаждени элементарной серой и другими несульфидными продуктами. Пример. Осаждение ведут из раствора сульфата никел с содержанием никел 10,4 г/л, рН 1,85 при 80° С и перемещивании в течение 1 ч. В качестве осадител используют раствор серы в известковом молоке, содержащий 200 г растворенной серы на 1 л раствора и металлическое елезо из расчета 0,75-1,0 г на 1 г осажденного никел . Показатели осаждени при 99%-ном извлечении никел в осадок без добавки металлического железа и с добавкой железного порошка, восстановленного водородом, при двух разных его расходах приведены в таблице. . The invention relates to hydrometallurgy of non-ferrous metals, in particular to methods for the recovery of heavy non-ferrous metals, for example copper, nickel and aqueous solutions by precipitating them as sulphides. There is a known method for the precipitation of nonferrous metal sulphides from aqueous solutions and sulphides by sulphidisadium 11. , By this method, the separation of colored sulphides. metals lead sulfur dissolved in any alkali. However, with this method, the content of non-ferrous metals in the final product is reduced, and the consumption of the precipitating reagent is high. The aim of the invention is to increase the content of non-ferrous metals in the final product and to reduce the consumption of the precipitating reagent. This is achieved by the fact that sulfidization is carried out by a mixture of metallic iron and sulfur dissolved in alkali. Metallic iron, which is simultaneously introduced into a solution containing non-ferrous metals with a solution of sulfur in alkali. creates in solution a redox potential that promotes the involvement of low-active forms of dissolved sulfur in the precipitation process. At the same time, the required consumption of jiacTBOpa sulfur in alkali is significantly reduced, and the final product is significantly less polluted by elemental sulfur and other non-sulfide products released during the precipitation process. Example. Deposition is carried out from a nickel sulphate solution with a nickel content of 10.4 g / l, pH 1.85 at 80 ° C and moving for 1 hour. A solution of sulfur in lime milk containing 200 g of dissolved sulfur per 1 l of solution is used as a precipitator. and metallic iron at the rate of 0.75-1.0 g per 1 g of deposited nickel. The deposition rates at 99% nickel extraction into the sediment without the addition of metallic iron and with the addition of iron powder reduced by hydrogen at two different expenses are shown in the table.

The composition differs from the known higher content of non-ferrous metal in the sediment and the mea- surem consumption of the sulfur solution in the oil is very good.
